The prevalence of hepatitis E virus in piglets on Czech pig production farms and phylogenetic analysis of recovered isolates

The aim of our study was to determine the prevalence of hepatitis E virus (HEV) in domestic pigs and to investigate the genetic divergence of swine HEV in the Czech Republic. To this end, a one-step real time RT-PCR assay was introduced as a screening method while nested RT-PCR was used as an additional method to obtain specific sequences from the HEV genome and thus to perform sequence analysi...

Detection of hepatitis E virus genotypes 3 and 4 in pig farms in Korea

Zoonotic transmission of hepatitis E virus (HEV) is mostly mediated by HEV-3 and HEV-4 genotypes, and domestic pigs are an important reservoir of these genotypes. A survey of 14 pig farms in Korea revealed HEV RNA in 30 of 148 (20.3%) fecal samples. HEV-3a and HEV-4c subtypes were identified in five pig farms (35.7%) and two pig farms (14.3%), respectively. Phylogenetic analysis indicated that ...

Molecular characterization of hepatitis E virus detected in swine farms in the province of Quebec.

Swine Hepatitis E virus (HEV) could be a zoonotic agent for HEV infection in humans. In Canada, approximately 60% of 6-mo-old commercial pigs are seropositive for HEV; the prevalence is higher in the provinces of Quebec and Ontario. A study was set up to evaluate the presence of swine HEV in Quebec farms and to compare the strains detected in fecal samples with human and swine HEV strains repor...
